SEALED RECEPTACLE.

Specification of Letters Patent.

Patented July 15, 1919.

To `all lwhom t may concern:

Be it know-n that I, ANDREW S. Nico, a citizen of the United States, residing at Le Roy, in the county of Genesee and State of New York, have invented new and useful Improvements in Sealed Receptacles, of which thefollowing is 'a specification.`

My present invention relates to improvements in paper receptacles, and the primary object of the invention is to provide a moisture-proof seal or inclosure for the contents thereof, the invention embodying a novel and improved sealv or inclosure which will eifectually retain the contents of the receptacle therein and will vexclude moisture from the interior of the receptacle. The seal or inclosure, according to the present invention, embodies a plurality of bends which are formed in the paper or material at the mouth of the receptacle, these bends forming sealing corners, and, preferably, means is also provided for lockingor retaining the bends in proper form or relation.

To these and other ends, the invention consists in certain improvements, and combi'nations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.-

In the accompanying drawing z- Figure l is a perspective view of a paper receptacle constructed in accordance with one embodiment of the present invention.

Fig. 2' represents a section taken transversely through the seal and on the line 2-2 of Fig. 1.

Fig. 3 represents a section, on an enlarged scale, taken longitudinally through a portion of the seal and on the line 3 3 of Fig. 1.

Fig. 4 is a perspective view of the upper portion of a sealed receptacle showingy al1- other embodiment 'of the present invention.

Fig. 5 represents a transverse section vthrough the seal shown in Fig. 4, and

Fig. 6 represents a transverse section taken through the receptacle and its seal and also through the carton in which the receptacle is packed for'shi-pment.

Similar parts-are designated by the same reference characters in the several views.

While the present invention is applicable to receptacles of various types Where it is desirable or necessary to seal or protect the contents from moisture and -to retain the contents vwithin the receptacle, it is partlcularly applicable to receptacles made inthe form of a bag and composed of moistureproof paper or similar materiall which isfolded in a manner to provide a suitable space for the contents and to bring all of the free edges of the paper or material together, the margins of the paper or material being then formed so as to seal the contents from moisture vand to retain the contents within the receptacle, means being also preferably provided for retaining the margins of the paper or material in sealing relation. A receptacle of this general type is shown and described fully in Letters Patent, No.

1,101,430, granted June 23, 1914, to Otis E.

Glidden and myself. The receptacle shown in the present instance is of the same type as that shown and described in said partent, but the present invention prov-ides a sealed closure which differs structurally from that shown in said patent and which possesses certain advantages thereover.A The preferred forms of closures or seals are shown in the accompanying drawing and will be hereinafter described in detail,but it isto be understood that equivalent constructions are contemplated and Will be included within the sco e of the claims.

n the present instance, 1 designates the body of the bag or receptacle, it being made up .from a blank in the manner shown and described in said prior patent, whereby the margins of the blank are all brought together at the mouth of the bag or receptacle. The receptacle or bag may be made of paper or any other suitable materiah, but it is preferably made of a paper which is impervious to moisture, a papercoated or treated with paraiin or a so-called waxed paper being preferable. Furthermore, in order to facilitate handling lof paper of this character in the machines which make up the receptacles, it is preferable to employ a paper which is waxed on the side only which is inthe receptacle when the same bodiments of the invention, by bending the margins of the paper or material at the mouth of the bag sharply along the line 2.

' tical dimension of the receptacle.

This sharp bending or creasing causes the lapped or engaged margins of the blank forming the receptacle to stand at an angle, preferably about a right angle, to the ver- A relatively firm compression is also preferably exerted upon the corner or bend 2, and this compression, in conjunction with the relatively sharp bend, causes the engaging and wax-covered surfaces to conform precisely to one another and to form a seal whic will exclude moisture from the receptacle and will prevent leakage of the contents, especially where the contents are in the form of a powder.

The portions 3 of the margin of the blank which extend laterally from the bend 2 and in a plane substantially at a right angle to the vertical dimension of the bag or receptacle lie in close relation to one another, and their free portion 4 is then bent downwardly along the line 5, the bend lbeing preferably at substantially a rightangle so that the portion 4 will project downwardly in a plane in substantially right angular re tion to the laterally extending portion 3. The bend 5, which is also relatively sharp, is also preferably subjected to compression which will cause the waxed surfaces of the lapped margins of the blank to conform precisely to one another and to form an air-tight seal. By bending the free portion 4 of the margins downwardly at substantially a`right angle to the plane of the laterally extending portion 3, relative movement of the lapped portions 3. in planes parallel to one another is prevented, and hence any tendency for the mouth of the bag or receptacle to open, particularly under the pressure of the contents thereof when the receptacle is inverted during handling or shipment, is effectually resisted.

The bend 5 also cooperates with the bend 2 to complete a perfect moisture-proof seal.

Suitable means is preferably provided for retaining the layers of the paper composing the downwardly extending portion 4 in engagement and for preventing relative shifting of these layers upon one another which would permit separation of these layers at the bend 5. As shown in Figs. 1-3 inclusive, tongues 6, of substantially dovetail form, are punched from the layers of paper or material composing the downwardly-turned portion 4. Preferably, and as shown, the wider portions of these dovetail tongues are at the free ends thereof,

. and the tongues are bent on lines 7 which extend vertically or in a direction transverse tothe line of the bend 5. The edges of the tongues coperate with the edges of the openings formed in the adjacent layers of.paper and thereby form interlocks which effectually prevent relative separation of the layers of paper at the bend 5. These tongues are preferably bent at substantially a right angle to the plane of the downturned portion 4 and they are preferably directed inwardly or toward the receptacle to protect them and to avoid the presence of projections on the receptacle which might be found objectionable. In order to prevent relative movement of the layers of paper composing the downturned ortion 4 in a horizontal direction, or a dlrection longitudinally of the portion 4, one or more of the tongues 6 may be struck from the portion 4 in a reverse relation from the remaining tongues, the bend of the tongues being in a reverse direction, and the lapping tongues 6 will then act, as will appear from Fig. 3, to prevent relative shifting of the layers of aper in either direction longitudinallyof t e seal.

In Figs. 4, 5 and 6, tongues 8, which are preferably of substantially dovetail form, are struck from the layers of paper in such a manner that these tongues will assist the bend 5 in preventing relative movement of the layers of paper in the laterally bent portion 3 in a direction that would permit opening of the package, and these tongues also prevent relative separation of the layers of paper in the laterally bent portion 3 or at the bend 5. As shown, these tongues 8 are punched from the transversely bent portion 3, the wider portions of the tongues being at the free ends thereof, and these tongues are bent downwardly along the lines 9 at substantially a right angle to the plane of the laterally bent portion 3 so that the tongues extend downwardly in parallelism with the downturned portion 4, or substantially so, and the tongues occupy a position between the downturned portion 4 and the body of the receptacle. Owing to the shape of these tongues, their free ends being larger than the ends thereof which are attached to the portion 3, the edges of the tongues will cowhich the tongues of adjacent layers are punched to prevent relative separation of.

the layers inthe vlaterally bent portion 3, and as these tongues are bent on the lines 9, they will supplement the action of the bend 5 in preventing relative shifting of the layers in the portion 3 which might permit opening of the mouth of the receptacle.

Fig. 6 shows one of the receptacles as it is packed Within a carton 10. The laterally bent portion 3 of the seal engages a wall 11 of the carton and it is thereby held in right angular relation to the vertical dimension of the receptacle, and hence inversion of the receptacle will not cause opening of the mouth thereof, notwithstanding the 'fact that the contents of the receptacle are brought to bear With some pressure upon the converging Walls leading to the mouth of the receptacle and which will tend to spread apart these walls and to open the receptacle. Relative shifting of the layers of paper in the laterally bent portion 3 under the same influence will be prevented by the second bend 5 and the locking tongues, as hereinbefore explained.

I claim as my invention l. A receptacle having its material at the y mouth thereof lapped and bent laterally at a sharp angle to form a sealing corner at said mouth and then bent downwardly at a second sharp angle at a point removed from the bend lirst mentioned, and means punched from said lapped material and serving as a lock to prevent slipping between the layers of the lapped material.

2. A receptacle having its material at the mouth thereof lapped and bent at approximately a right angle to form a relatively sharp sealing corner, a portion of sald material extending laterally from said corner, and the material at the free edge of said laterally bent portion being bent at approximately a right angle to form a second relatively v'sharp corner, and means punched from the lapped material and serving as a lock to revent slipping of the individual layers o the lapped material.

3. A paper receptacle having its material yat the mouth thereof lapped and bent laterally at a sharp angle to form a sealing corner at said mouth, said laterally bent lapped portion being thence bent at asecond relatively sharp angle at a point removed from the bend lirst mentioned, and dovetail tongues punched from said lapped material and serving as locks to prevent relative slipping between the layers of the lapped material.

In testimony whereof I have hereunto set my'hand.

ANDREW S. NICU.
